After reading Robin’s post yesterday about her dog being attacked by off-leash dogs, I remembered seeing the Dog Dazer while surfing the Sky Mall site. The Dog Dazer emits a high-frequency sound that’s painful to dog’s ears, but inaudible to humans. Use a 1-2 second burst to startle and hopefully deter a threatening dog from as far as 20 feet away. Of course, I’d probably want some pepper spray as well, just in case. The Dog Dazer is $59.95. Sky Mall also has the Dog-Off Deluxe version, which adds a belt clip, flashlight, and an audible alarm to also deter human attackers. The Dog-Off Deluxe is $69.95.
